That helps. Do you have any idea why the foundry wont let me do story mode though?

Me and my buddies want to do all the flashpoints. I know now that not all flashpoints have story mode (which I think is dumb because I played a long time ago and more of them were then) but I dont know which ones do. We're imperial characters and I'm level 34. We've successfully done black talon and boarding party but even the foundry (which I have a quest for) will only let us do veteran mode. How do I get the Foundry in story mode and which flashpoints are available in story mode?
